Okay, the difference between the SS (transformer) and tube mods is one of 'voicing' and tonality.
Our Tube mods are not characteristically 'tubey' in that they do NOT roll of the highs or soften the bass. They do, however, give a certain amount of warmth and tube 3-dimensionality.
The SS (transformer) mods are more neutral and offer a greater level of micro-detail, resolution and tighter bass response. I would describe this presentation as more 'accurate' but lacking the tube warmth and holographic qualities. This mod will appeal to those who prefer solid-state systems. It is ruthless of poorly recorded material, but presents excellent recordings in a VERY realistic way.
To be clear, both mods are true to the music and the tube mods do not 'color' the sound significantly, but tubes DO add their own sonic character. There is a 'magic' and 3-dimensional quality of tubes that cannot be matched by solid-state equipment, in my opinion. This is preferred by many but not all. The SS mods are available to suit the tastes of those who prefer the qualities of solid state gear over tube gear.
The solid state mods are less costly as they do not require the outboard supply and involve less parts cost and labor. The SS mods also DO NOT buffer the output, so it will work best WITH an ACTIVE preamp, rather than a passive attenuator. It will work very well however, with an integrated amplifier, provided that long cable runs are not used - i.e. < 2m-3m. runs.
I am ready to start taking pre-orders now and scheduling start dates. We will require a 50% deposit up front to reserve a firm start date, but these will be scheduled to insure short turnaround time.
Thanks,
Dan W.
